Bet this flop?

[spacemonkey57]

I just moved up to 1/2 and I feel like I've been playing too weak tight because of the new massive stakes. I could post stats, but I've only got 1000 hands in so that's pointless. Is this weak play on the flop? Or is check/folding a decent line against 5 opponents.

Third hand at the table. It had been kind of loose/wild in the first two hands. Should I be betting this flop? Thanks.

Seems like a standard bet, going for the C/R is risky with only 2 others behind you and no preflop raises

Unless you were trying to check-raise, in which case I would say click that check-raising works better when you click the raise button /images/graemlins/wink.gif

I would definitely bet this flop. That was a weak tight fold, unless you know MP3 is super passive or only bets with the nuts. There are tons of hands MP3 could be betting including anything with a 2, or, more likely, overcards, or overcard. There are onl 2 nines in the deck. Chances are no one has one. Do you bet this at .5/1?
